How to deal with Soulmass?

I'm incredibly salty about this spell. I feel like if gives you no fair options against it.

I've started meeting more sorcerers at SL120, and although some just try to do the typical soulmass + CSS to one shot you, there's the couple that try to fire off their soulmass when you don't expect it and hit you for insane damage without even using the CSS.

That's my issue. If you try rushing them and approaching them, you get hit by the soulmass (and worst part is that they don't lose them...), and sometimes they fire off on their own without the sorcerer being locked to you. If you don't rush them and stay back, then you're vulnerable to eating huge damage from the soulmass at any moment or any other spell, and you have nothing but rolling sideways against it.

Everyone complains about how bad sorceries are but this one's ridiculous. You can do nothing against it except try to force them to shoot it and dodge it. Pray you knew when it was firing or have inhuman reflexes to i-frame through them. And that they don't decide to use Farron Flashsword in your face. Oh, and then you'll have to pray that they don't just cast another Soulmass. Or that they don't mix it up and cast a CSS instead.

Spoiler: they will.

EDIT: I realize that the more soulmass-relying playstyles I found are still rare and so people here either won't exactly know of what I'm talking about (thinking I mean how to avoid it from 10m away and only have to once) or can't help much because they haven't had any experience against them. I have the impression that this kind of sorcerer playstyle's gonna become popular and known soon.
